Abstract

Plasmonic response of superconductors at various dimensions are addressed in this paper. All possible parameter space is discussed and considered for theoretical demonstration towards possible future experiments. The most critical parameters in each dimensional state are found to be carrier concentration (3D), wavevector (2D), surrounding permittivity (1D) and particle radius (0D). However, it is also demonstrated that unless all parameters combined with optimal conditions, the superconducting plasmonic system does not result in an ideal lossless environment. Furthermore, under all conditions, lower temperature decreases the loss content affiliated with electron and phonon scattering.
